WATER-H EATER AND STEAM-G EN ERATO R.

SPECIFICATION forming part of Letters Patent No. 610,554, dated September 13, 1898. Application filed November 6,1897. Serial No. 657,675- (No model.)

To all whom it may concern/.-

Be it known that I, J AMES MOCARTNEY, of

Oakland, in the county of Alameda and State of California, have invented anew andIm proved Water-Heater and Steam-Generator,

of which the following is a full, clear, and 6X1 act description.

The object of the invention is to provide a new and improved water-heater and steamgenerator, arranged to insure a proper circulation of the water, which when the heat is applied to the best advantage causes a quick heating of the water at a comparatively small expenditure of fuel.

The invention consists principally of a conical water-chamber the base of which is arranged directly over the burning fuel in the fire-box and a spreader within the said chamber above the said base and having a central inlet for the water to enter thechamher, the sides of the spreader forming, with the sides of the chamber, an upwardly-extending outlet for the heated water.

The invention also consists of certain parts and details and combinations of the same, as

- will be fully described hereinafter and then pointed out in the claims. r

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi-' oate corresponding parts in both figures.

Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a like view of "a modified form.

The improved water-heater is provided with an annular water-inlet chamber A, formed by vertically-disposed spaced walls B and 0, set

at their lower ends on a suitableobase D,

which supports the entire heater, The chamher A is very narrow, as is plainly indicated in Fig. 1, and is provided near its lower closed end with an inlet-pipe E, connected with a suitable water-supply or with the ,return pipes of a hot-water-heating system, so that the water entering the chamber A rises therein and flows between the tops 0. B of the walls 0 and B around a head 0 extending centrally between the tops 0 and B, the said 'head being provided with a smoke and'gas outlet opening 0 connecting the interiorof the fire-box formed by the wall 0 with a smoke-flue F, as is plainly shown in the drawings. In the head 0 is also formed a channel O for allowing the water between the I, supported by the base D, previously mentioned ,the burner being arranged in the lower end of the fire-box formed by the wall 0.

The conical Water-chamber H is provided with a spreader J, likewise made conical and .arrangedwith its base J, directly over the ,base H, so that the water passing through the pipe G into the space .between the bases J H is caused to spread in all directions in the said space to finally pass upward between the sides J 2 H of the spreader J in the chamber H'to short pipes K, connecting the sides of the said chamber H with the interior of a dished section L, connected in turn near its upper end by pipes K with an inverted dished section L, connected by pipes K with a section L similar to thesectionL. This section L is connected by pipes K with an inverted dished sectionL and pipes K connect the upper end of this section with an inverted top section L, from which leads an outlet-pipe N, connected by an elbow N with adistributing-pipe N? for carrying the water or steam to a desired place. The outlet-pipe .Nextends through the head 0 into the smoke .stack or flue F, through the side of which extends the distributing-pipe N Now by the arrangement described the elbow N can be turned in any direction to bring the distributing-pi pe N into the desired position, it being understood that the flue F, on account of being movable in the top B, allows such adjustment.

It is evidentthat when the water passes into the chamber H it isquickly heated by the heat emanating from the burning fuel, and the water readily flows up between the sides J? H and rises through the, pipes K into thenext section L, from which the water rises to the. pipes K to the followingsection. This is repeated until the water finally reaches the outlet-pipe N. As all the sections are disposed in the fire-box formed by the wall 0, it is evident that the heat arising in the fire box or chamber comes in contact with the outer surfaces of the several sections and pipes, and consequently continually takes up the units of heat, finally reaching the outlet-pipe N in a highly-heated state or in the form of steam, as the case may be.

It will be seen that by the arrangement described the water is free to circulate through the several sections without danger of being left therein, and it isalso evident that the 1 water rising in the chamber A is heated by the heat passing up the fire-box and heating the inner wall 0', so that the incoming water takes up considerable heat before it flows down the pipe G into the chamber H, in which it is subjected to the intense heat from the burner I, owing to the location of the burner relatively to the chamber.

7 Suitable burner devices must be provided for-such, for example, as those described below, which are preferred.

The burner I (shown in Fig. 1) is provided with a perforated top plate I, supported on a dished bottom 1 resting on the base D, and from the bottom I extends downwardly a cylindrical offset 1 containing an inner chamber 1 having a closed bottom with an airinlet pipe '0, provided at its top with a conical flange 0, extending under the burnerplate I. This burner forms the subject of a separate application filed by me February 24, 1898, Serial No. 671,526.

Into the chamber I opens the reduced end of a gas-mixing chamber P, connected at its I base with ages-supply pipe Q, having a suitable valve Q and a head Q extending centrally into the mixing-chamber P and having its inner end plate Q formed with perforations, as is plainly shown in Fig. 1. The valv'e Q has its stem connected by a rod R with the stem of the valve E on the water- 'supply pipe E, and on the rod R is secured a handle R for turning the rod and the valves E and Q simultaneously to turn on the water and the gas at the same time.

P for the admission of air and controlled by a perforated damper P mounted to turn on the inner end of the pipe Q, as shown in the 'drawrngs.

Now by the arrangement described air =can be mixed directly with the gas in the chainber P, and this mixture passes through the chamber A pilot-light coming from the gas-valve Q may be employed for igniting the mixture "on the top of the plate I.

let of the mixing-chamber P, Iam enabled to The base of the chamber P is also provided with apertures I conveniently shut off the air-supply com pletely at the mixing-chamber when lighting the burner, so as to prevent a sudden explosion in the chamber and an igniting of the gas issuing through the perforation in the end plate Q When the gas is lit, then the damper or air-valve P is opened to admit air to the mixing-chamber and insure a perfect blue flame of high heating qualities. In extinguishing the flame at the burner the air valve or damper is first closed to turn off the airsupply, and then the valve Q is closed to allow the pure gas-flame to die out slowly.

As shown in the drawings, the chamber H and the different sections L L L L L are made in parts bolted or otherwise fastened together, one section being connected with the other by pipes, as before described, whereby the hot air is free to pass to both the outer top and bottom surfaces and up through the open centers of the sections to insure a proper heating of the water as it rises in the sections.

- The adjacent sections L and L may also be fastened together by suitable bolts L", passing through hollow connecting-lugs L L", forming part of the adjacent sections L L, respectively, as indicated in Fig. 3.

The entire apparatus is preferably inclosed within a suitable shell 8, as indicated in Fig. 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A water-heater comprising a water-inlet chamber formed by vertically-disposed spaced walls, of which the inner wall forms a firebox containing a burner or grate, the said walls being spaced to allow the water to rise from the chamber to the said space, pipe depending from the top of the inner wall, to allow the water to pass from the space into the pipe and down the-same, a-conical waterchamber arranged with its base directly over the burning fuel in the said fire-box, and a spreader within the said chamber above the said base, and having a central inlet connected with the said pipe, to aliow the water to enter the chamber, the sides'o'f the spreader forming with the sides of the chamber an upwardly-extendin g outlet for the heated water, substantially as show-n and described.

2. A water-heatercomprisinga water-inlet chamber formed by vertically-disposedspaced walls, of which the inner wall forms a firebox containing a burner or grate, the said w'ails being spaced to allow the water to rise from the chamber to the said space, a pipe depending from the top of the inner wall, to allow the water to pass from the space into the pipeand down the same, a conical waterc'hamber'ar'ranged with its basedirectly over the burning fuel in the said fire-box,a spreader within'the said chamber above the said base,
